find the equation of a line which has a slope of -9 and crosses the y axis at -7
(BRAINLIEST +10pts!!!)
Answer: y=-9x-7
Step-by-step explanation:
The formula to write an equation in slope intercept form is y=mx+b.
m is the slope, b is the y intercept.
m= -9
b= -7
y= -9x+-7, which simplifies to
y= -9x-7

The frequency table shows the height ,in inches ,of 12 gymnastic.What fraction of the gymnastics are 59 inches or shorter?
Answer:
can you show the table. .
The formula F = 1.8C + 32 gives the temperature in degrees Fahrenheit (F) for a given temperature in degrees Celsius (C). There is one temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius. Complete the equation you can solve to find that temperature and then use it to find the temperature. Use the variable C to represent the number of degrees Celsius where degrees Fahrenheit and degrees Celsius are the same.
The equation is _____ =_____ + _____.
The temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius is _____°C.
Answer:
40 C

explain how to solve for the missing side from the similar figures given and solve. (do not just give the answer)
Answer:
x=14
Step-by-step explanation:
Since the triangles are similar, you first line up the sides. Then, because the 16 and the 24 line up together, you divide them to find out how much bigger the first triangle is, which is 3/2 or 1.5. After that, you can see that the 21 and the x are on the same side, so you would divide 21 by 1.5 or 3/2 to get x. 21÷1.5=14.
x=14
Answer: X= 14
Step-by-step explanation: line AC equals 21 and line BC equals 24, i put 24 over 21 like a fraction then i look at the smaller triangle now EF is proportionate too BC so next to the 24 i put 16 and line DF is X so you put X underneath 16 and next too 21. now you cross multiply and divide leaving you with 14 so line DF or X is 14

-- i am not sure about this, but i tried.
f (x) = 2x + 5
Clearing x we have:
2x = y - 5
x = (y-5) / 2
Rewriting:
f (x) ^ - 1 = (x-5) / 2
Evaluating x = 8:
f (8) ^ - 1 = (8-5) / 2
f (8) ^ - 1 = 3/2
Answer:
f (8) ^ - 1 = 3/2

Kevin is making a picture frame. He has a piece of trim that is 4 feet long.How many 14−inch-long pieces can Kevin cut from the trim?How much of a foot will he have left over?
First, convert 4 feet into inches - 48 inches. Then, divide 48 by 14 to get 3.43, so he can have 3 14-inch long pieces. To get the left over out of a foot, take 14 x 3 to get 42, then subtract 42 from your original 48 inches to get 6 inches left, which is half of a foot.
Answer:
3 pieces and 1/2 of a foot
Step-by-step explanation:
1. 4 feet converts to 48 inches. (4 X 12)
2. 48 inches divided by 14 can make three pieces
14+14+14=42 inches.
3. You will have 6 inches left over, and 6/12 is half of a foot :)

An architect makes a model of a new house. The model shows a tile patio in the backyard. In the model, each tile has length
and width
The actual tiles have length
and width
. What is the ratio of the length of a tile in the model to the length of an actual tile? What is the ratio of the area of a tile in the model to the area of an actual tile? Use pencil and paper. Describe two ways to find each ratio.
The two ways to find the ratio of the length is to turn the inches into feet or the feet into inches
So the answer can be solved like this:
1/36ft to 1/4ft which is 9:1 (blueprint size to actual size)
or
1/3in to 3in which is also 9:1 (blueprint size to actual size)

What is the perimeter of quadrilateral A' B' C' D'?
Explanation:
Quadrilateral A B C D is translated 2 units to the left and 5 units down to create quadrilateral A' B' C' D'.
Answer:
14.2 Units
Step-by-step explanation:
The second shape is given to confuse you and is not actually necessary.
To work out the perimeter of an irregular shape you simply add up the lengths of each side. The shape you have here is an irregular quadrilateral as it has four corners and no recognisable/coarrale organisation.
1.4units + 2.2units + 4.5units +6.1units = 14.2 units.
